Evaluating Stabilizers Effects on Aroma Release Dynamics in Ice Cream: A PTR‐ToF‐MS Analysis

open access: yesJournal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Capturing the dynamic volatilome of frozen matrices during phase transitions remains an analytical challenge, typically requiring invasive sampling. This study employs proton transfer reaction time‐of‐flight mass spectrometry (PTR‐ToF‐MS) as a rapid, noninvasive technique that directly samples headspace volatiles without preconcentration to ...

Application of In-Syringe Dispersive Liquid–Liquid Microextraction and Narrow-Bore Tube Dispersive Liquid–Liquid Microextraction for the Determination of Trace Amounts of BTEX in Water Samples [PDF]

open access: yesJournal of Chromatographic Science, 2015
Two new simple and effective methods based on dispersive liquid-liquid microextraction (DLLME) procedure, termed "in-syringe DLLME (IS-DLLME)" and "narrow-bore tube DLLME (NB-DLLME)", were developed and applied for rapid and simultaneous separation and preconcentration of trace amounts of benzene, toluene, ethylbenzene and xylene isomers in water ...

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5689-5702, August 2026.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

Sustainable Ball Milling‐Assisted Synthesis of Bread Waste‐Derived Highly Porous Carbons for Adsorption‐Based Applications

open access: yesChemPhysChem, Volume 27, Issue 13, 14 July 2026.
A simple strategy is proposed to convert food waste such as dry bread into highly porous carbons that can be used for catalysis and adsorption‐related applications. Namely, a fast ball milling of dry bread and a mild activation agent, followed by carbonization at 800°C, is used to obtain porous carbons with surface areas up to 2400 m2/g.

Shaping Carbon Nitrides for Advanced Macrostructures

open access: yesAdvanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose

open access: yesDrug Testing and Analysis, Volume 18, Issue 7, Page 877-892, July 2026.
A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.
